FWINDING-MACHINE.

' Patented Dec. 5, 1905 Application filed May 251902. Serial No. 108,825.

To a, whom it may concern Be it known that I, SIMON W. WARDWELL, a citizen of the United States, residing at Provijdence, county of Providence, and State of v Rhode Island, have inventeda newand useful fication and illustrated by the accompanying drawings, of which- Figure 1 represents a portion of a windingmachine, showing the thread-guide and trav- 5 erse-frame and the relation of my invention thereto; Fig. 2, an end view of the outer disk or head for supporting the cop, showing the preferred means of removably attaching it to the cop-tube carrier; Fig. 3, a section of the 3 outer head, taken on the line A A, Fig. 2, and showing the preferred device for securing in place the said outer head. Fig. 4: is a sec-- tional view of the tube-holding device extending through the ring'm on the line B B, Fig.

3-5 8, showing the devices whereby the tube, is

. retained by or disengaged from the tubeholder and also an alternative means forretainingthe head a; Fig. 5, an end view showing in operative position the alternative 4 means for retaining the head n; Fig. 6, an end View of the tube-carriera looking in the direction indicated by arrow C; Fig. 7 ,a view of the inner head of the carrier removed, also looking in the direction indicated by arrow C;

" Fig. 8, an end view of ring at looking in the same direction.

One preferred form and arrangement of my invention is shown applied to a tube-holding device such as is described in my Patent No. 5 690,493, recently issued, in which the tubecarrier is formed with expansible 'staves or segments, whereby the tube is secured.

The tube-holder is arranged between heads ordisks 6 n, the latter at least removable, and the guide 8traverses at each movement the length of the holder in contact with the cop, so as to gradually move outward as the packageincreases in diameter, the heads preventing any such lay or disposition of the threadas would result in a cop with bulging ends. To this end the traverse-frame which supports the guide is shortened, so that it may pass between the heads as, it swings in and out and afford a support on which the guide may travel the length of the package between the heads at each movement.

While the heads or disks may be mounted and secured in any suitable manner on the spindle, I prefer to use the means I will now describe.

On the base end of the tube-carrier a, as

shownin Fig. 4, is mounted a disk or head 5,

fixedly secured to alternate segments 0, leaving the intermediate segments d' free to be expanded and secured from turning by the twoprojections e, which engage the holes f in two of the segments 0.

Mounted on the winding-shaft of the machine to whichthe tube-carrier is'secured is the sleeve g, Fig; 4, adapted to be shifted longitudinally thereon by means of the lever h, Fig. 1, to effect the expansion of the free segments d, 'which'latter have internal projections 'ito engage the ring j of the sleeve g d are sufficiently shorter than the segments 0 to permit the ring m to be passed and protruded through the head J). This is for the purposeof disengaging the completed package from the tube-carrier. The tube on which the package is wound when secured to the tube-carrier extends up to the head I), and the projections Z as they protrude through the head 6 engage the tube after it has been released from the segments (Z and shift it on the carrier to disengage it therefrom.

The outer head n is provided with a hub 0, by which it is mountedv on a stud or projection 9 of the tube-carrier. The recess q accommodates the portion of the tube which projects from the end of the package, thus permitting the head a to be brought close to the end of the package.

To provide for placing the cop-tube upon the carrier and for removing the completed package therefrom, the head a is so secured as to be easily removed. This may be accomplished by various suitable meansas, for instance, one of those now to be described.

As shown in Figs. 2 and 3, at the outer end of the hub n is supported a cup-shaped member or cap 7*. The latter is rotatable on its bearing 3, which is a portion of the hub 0, formed eccentric with the axis of the head 0% and the tube-carrier. The cap r is retained longitudinally by a pin t, fast in the hub 0 and engaging a suitable slot in the cap. In the end of the cap 1" is a circular opening a of appropriate size to slide freely over the tip 10 of the projection p, which is slightly reduced in diameter from the main portion on which the head has its bearing. The opening 1/. is of less diameter than the main portion of the projectionp, so that the latter serves as a stop to limit the extent to which the head a can be slid on its bearing. Between the main or bearing portion and the tip of projection 11 is a circumferential channel 2; of appropriate width to receive the end of the cap to retain the head a in position. The opening a is formed eccentric to the axis of the bearing 8, on which the cap 1" turns, and so related thereto that the turning of the cap will bring it in line with the axial hole in the hub 0. At the inner end of the cap is a recess or channel to, adapted to receive a coiled spring w, secured with one end fast in the cap and the other in the hub 0. The spring 00 maintains the cap normally in the position indicated in Fig. 2, with the opening a eccentric I to the tip of the projection 19 and the annular flange y in engagement with the groove 4). The action of the spring is limited by the pin 2. contacting with the end of its slot. The

latter is of such length that its opposite end contacts with said pin to prevent the turning of the cap beyond a point where the opening shall be concentric with that of the hub. The

periphery of the cap is normally concentric with that of the hub and may be knurled to aflford a good handhold.

The operation of the device is as follows;

that in the hub. The head is then slid onto the projection 10 until the end of the cap contacts with the end of the main portion ofthe' projection 9, at which point the flange 7 of the cap is forced by the spring into the groove '0. The engagement of the cap with the groove retains the head in position. To remove the head a at the completion of the winding, it is necessary only to turn the cap until its opening is concentric with and free to slide over the tip of the projection 12.

A modification of the retaining devices is shown in Figs. 4: and 5, in which the head a is retained by a spring-catch 2, which is adapted to simply move transversely on the end of the hub 0.

The use of removable retaining-heads is not per 86 new in the art of winding, a usual mode of winding some cords having been to wind between heads and before removing the latter to bind together the material wound by a series of ties. In such devices, however, the heads or flanges formed a part of a removable spool, which latter must be disassembled to remove the material wound and reassembled and replaced in the machine before again commencing the winding.

By means of my device it is possible to wind upon the usual inexpensive paper tube, and as the heads I) and it constitute really a part of the tube-carrier a and are used in conjunction with the devices for quickly securing the tubes or dofling the packages materials can be wound that could not otherwise be wound expediently, if at all, for scarcely any more time is consumed in removing the head 72 than is required to remove a'tube or package alone.

The device is particularly valuable in winding certain materials which are so slippery and elastic that they cannot be wound without excessive bulge. By winding such materials between heads in the manner described well-formed cops are wound, which when released retain their shape indefinitely.

Without limiting myself to the precise form of structure or arrangement and correlation of the parts employed, I claim as my invention 1.
